ANTISKID DEVICE.

Application filed October 8, 1921.

T aZZ whom 2'25 may conccrn Be it known that we, (1) THOMAS E. Mc- SHAFFREY, (2) CHARLES F. GILBRIDE, citimens of the United States, residin,q at Akron,

in the county of Sunnnit and State of Oliio,

have invented a certain new and usefu] Improvement in Antiskid Devices, of which the following is a full, clear, and exact description, reference being had to the accomPanying drawings.

This invention relates to anti-skid devices and has particular reference to devices of this character which are suitable for use on rubber tired vehicles, such as automobiles and motor trucks.

Some of the objeots of the present invention are to provide an anti-skid device which may be easily and quickly applied or re- -moved from the vehicle wheel and which,

when in position, shall be effective in preventing skidding of the vehic1e; to provide a device of this character which shall be exceedingly simple in construction, strong and durable, and inexpensive to manufacture,

while urther objects and advantages will appear as the description proceeds.

In the accompanying drawing Wherein we have shown one form of our invention, Fig. 1 is a fragmentary side elevation of an autom- 1nobiie wheei fitted with one of our anti-skid devices; Fig. 2 is a scctional view taken on the ]inc 2 2 of Fig. 1: and Fig. 3 is a perspective view of: a half of one of the spoke co]lars.

Describing by reference characters the various parts illustrated, 1 denotes the felly of a whee1, 2 the spokes, and 3 a pneumatic tire. Those parts may be of the usual or any ap proved construction.

Seoured about a seiocted uumber of the spokes, or about al] if conditions require it (one bein shown n the drawin as sufiicient for illustrative purposes). are spoke collars made up of halves 4., 4 which are identica] in construction and hence are interchangeable. Each half collar 4 is composed of a semi-oviindrica] bodv portion 5 which is formed at each end with a fastening lug 6, and intermediate said lugs. with an integral projection 7. The projection 7 is slotted as indicated at 8, to receive the shank 9 of a hook 10. A rivet 11 extends throngh a spring tongue 12, shank 9 and projection 7 and secures said parts in tight relationsh ip Serial No. 506,248.

thereby t0 constitute o: i'iN, book and fougue a snap of common form.

Eaoh collar is clamped about its respective spoke adjacent the feHy by means or. suit able bolts, indicated at 14, and a bushing 15 of soit compressible material, such as rubber or leather is interposed between the spoke and the halves 4: of the collar, to prevent chafing or the spoke. The bushings 15 are shown as having end beads to secnre them against dislodgment.

The collars are positioned on the spokes so that the snap hooks 10 project outwardly on opposite sides of the feHy in transverse alignment. A chain 16 or other suitable traction element extends transversely over the tire and has its ends engaged over the snap hooks of each co11ar, as clearly shown in Fig. 2.

As hereinbefore stated, collars may be olamped to all the spokes, or to any desired number of them, as for example, t0 alternate spokes of the Wheel; and as these collars do not interfere with the removal of the ri1n or tire from the wheel it is intended that they romain on the snokes at all times. Remova] of the anti-skid elements is easily accomplished as it is only necessary to discngagze the ends of the chain from the snap hdoks. VVith the Wheel equipped with its prescribed a]iotment of coilars, any number o:[ anti-skid elements or chains (up to the numbcr of collars) may be applicd to the Wheel according to the conditions under which they are to be used.

IIaving thus described 0111 invention, what we clai1n is:

1. A device of the character set forh cornprising a pair of substantiaily se1ni-cylindrical members adapted to be securod about the spoke of a wheel, ]ugs projecting i'rom the ends of each of said 1ne1nbers, boit exend ing through the corresponding luge of the opposed members, a nui; threaded on each boit and adapted 1o draw said 1nembers together about said spoke, a projection for1ned on each member intermediate the luge thereof, a snap hook extending outwardiy from each member and having a shank riveted to said projection, and a traction ee1ncnt engagcd over the tread of the Wheel and having its ends secured to said snap hooks.

2. A device of the character set forth comprising a pair of substantialiy se1ni-cy1indrical members adapted to be secured about the spoke of a wheel, lugs projecting from the ends of each of said 1ne1nber5, fastening means extending through the correspondng lugs of the opposed members, a projection formed on each member intermediate the lugs thereof, sad projections being slotted and each having a snap hook positioned therein, and a traction element engaged over the tread of the wheel and having its ends secured t0 sad snap hooks. 10 In testimony whereof, We hereunto affix our signatures.
